[sdiy] Frequency Counter advice...

[David Ingebretsen]

Mundane things like volts, ohms, farads, semi conductors, temperature, etc.,
trouble shooting like any other volt meter. But the precision gives me 1/10
of a milivolt readings, so it helps with calibrating VCO's, Midi 2 CV, and
other voltage sources.
